Quartz clock movement of the quartz crystal sensor is the core of sensors, piezoelectric electron wafer, its working principle is the piezoelectric effect, namely the quartz crystal in some direction by mechanical stress, will produce electric dipole; On the contrary, if a voltage is applied in one direction of quartz, the deformation will occur in its specific direction, which is called inverse piezoelectric effect. If an alternating electric field is applied to a quartz crystal, the crystal lattice will produce mechanical vibration. When the frequency of the applied electric field is consistent with the natural oscillation frequency of the crystal, the crystal resonates. Because of the quartz crystal under pressure output of the electric field strength is very small, so only very weak applied electric field can produce deformation, this feature makes the piezoelectric quartz crystal is very easy to produce resonance under alternating electric field with excitation. Its oscillation energy loss is small, very stable oscillation frequency, the coupled with quartz excellent mechanical, electric and chemical stability, make it become since 40 s quartz clock movement, electronic watch, phone, TV, computer and other related to digital circuit of frequency reference element
A clockwork is a part that provides energy for a watch. Circle around the box. Use the milling slot on the bar shaft to tighten the spring. The square groove of the bar shaft is driven by the upper mechanism. The watch can walk for about 36 to 50 hours without rewinding. Because the spring is subjected to obvious stress, it often leads to fracture, so at present, alloy material is used to make the spring almost unbroken. The spring stores a certain amount of energy to distribute evenly and in small quantities to the oscillator. For this purpose, the energy provided is reduced by the same proportion of the transmission force and the number of cycles is increased by the rotation group through the rotation group. The wheel train consists of four wheels and four gears, the last three wheels are riveted on the first three gears. In this diagram, the oblique line indicates the meshing between the moving parts, while the horizontal line indicates that the moving parts are riveted on the same axis. The first wheel is a box wheel with circular teeth milling. The last wheel is the escapement gear, which is riveted by the escapement gear. The escapement wheel belongs to the distribution mechanism and counter. The box turns around for about 6 hours, during which time the escapement gear and escapement gear rotate about 3,600 times. This number represents the ratio of the rotation frequency between the first wheel and the last wheel. The ratio is always within this range. It is common to try to keep the gears and wheels in the center of the watch and turn them once an hour.
First, the crystal in the quartz watch is charged, and the crystal will vibrate correctly at 32,768 hz. This frequency must then be reduced to 1Hz (a change in the current per second) of the signal current cycle. Add some signal amplitude (due to the current is very weak due to vibration), followed by some signal current and rotor gear, the second hand on the table will be launched, then after a minute hand and hour hand beat is about the principle of mechanical structure. Such as: beats 60 times a second hand, minute hand will jump.
All quartz watches are fitted with a battery. It provides energy for an integrated circuit and a quartz resonator that vibrates 327,678 times per second. There's faster than that. An integrated circuit is the brain of a watch. It controls the vibration of the quartz resonator and ACTS as a frequency divider. The 32,768 vibrations were cut in half 15 times to generate one pulse per second. With a second of kushiro this time "raw material", can drive the display
